北京市远郊区的十个县,有七个是山区,在1975年底尚有409个大队不通汽车(占山区大队总数的33.4%)。在全国农业学大寨会议以后,北京市委为了迅速改变这些大队交通的落后状况,提出了从1976～1978三年内做到大队都通汽车的规划。四年来,大打了一场建筑山区公路的人民战争,动员之广,规模之大,进展之快,修建里程之长,在我市远郊筑路史上都是空前的。 Seven of the ten counties in the outskirts of Beijing are mountainous. By the end of 1975, 409 brigades were inaccessible (33.4% of the total number of mountain brigades). After the conference on agriculture in China, the Beijing municipal party committee put forward a plan to build a bus between the two sides from 1976 to 1978 in order to rapidly change the backwardness of these brigade traffic. In the past four years, we have fought a people’s war building mountain roads. The mobilization is extensive, the scale is large, the progress is fast, and the length of the construction mileage is unprecedented in the history of road building in the suburbs of our city.
